Fletchinder are avian Pokemon with predominantly orange and black plumage. They have a sharp, black beak and a small, pointed crest atop their heads. They have black eyes with yellow, mask-like marks extending from the back. Their uppersides are reddish-orange and their bellies are gray, with a flame pattern marking the boundary on the breast. Their pointed wings are black with yellow tips and undersides. Their legs are also black, and they have sharp talons with two toes forward and one back. They also have long black tailfeathers marked with two white "v"-shapes. The tail ends in two points and has a another feather sticking out of the base on each side, giving the impression of the fletching on the end of an arrow.
These Pokemon have a flame sac in their bellies. As their internal fire gradually heats up, they are able to fly at increasingly faster speeds. Fletchinder are known to hunt by igniting tall grass and swooping down on prey that attempt to escape the blaze.
